There are 9 sigma ($\sigma$) bonds and 9 pi($\pi$) bonds

#### Explanation:

Each cyanide contains a triple bond from which one is sigma and two are pi

There are four cyanide so
Total sigma bonds= 4
Total pi bonds = 8
There are four carbon to carbon single bond
Number of sigma bonds = 4
At last there is a double bond between two carbons thus
Number of sigma bonds = 1
Number of pi bonds = 1

Adding all these we get 9 pi bonds and 9 sigma bonds

Hope it helps you
